SPECIFICATION forming part of Letters Patent No. 749,039. dated January 5, 1904 Application filed April 13, 1903. Serial No. 152.322. (Nn model.)

[0 all whom it r11/wy concern.-

Be it known that l, VEAT J. DOLECHEK, a citizen ofthe United States,residing at Clatlin, in the county of Barton and State of Kansas, have invented certain new and useful Improvements in Motion-Transmu ters, of which the following is a specification.

My invention relates to improvements in machines for converting reciprocating into alternating rotary motion; and one of my objects is to utilize the power of windmills or other motors for the purpose of running washing-machines and other machinery requiring but little power for their operation.

A further object is to relieve the pitmanrod of the compression strain to which it is subjected on the downward stroke and which owing to its great length it is but ill adapted to resist.

Another object is to construct the machine in as simple'a form as possible, so the greater portion of the power transmitted from the pitman-rod will not be utilized in propelling fly-wheels, ratchet-wheels, dac., before finally reaching the point of use.

To this end my invention maybe said to consist in the novel arrangement and combination of parts hereinafter described, and pointed out in the claims.

Referring now to the accompanying drawings, which illustrate the invention, Figure 1 represents a side elevation of mycomplete machine, showing its operation by dotted arrows. v Fig. 2 is a plan view of the same, partly broken away. Fig. 3 is a detail side elevation of a segmental cog-gear forming part of myinvention. Fig. 4 is a detail vertical section taken on line IV IV of Fig. 1.

In constructing the machine I employ a frame comprising transverse foundation-timbers 1, standards 2, connected by lower longitudinal timbers 3, intermediate timbers 4, upper timbers 5, and transverse timbers 6. Timbers 5 extend outwardly from one end of the machine and are supported at their outer ends by braces 7 for the reception of a bellcrank lever 8, fulcrumed at 8a in bearings 9, secured upon timbers 5. The opposite ends of bell-crank lever 8 are secured together by a brace 8b, and its upper end is pivotally connected to a pitman-rod 10, from which it receives its motion,while its lower end 8f1 is pivotally secured to a connecting-rod 11, pivotally connected at ils upper inner end to au arm 12,formed integral with a segmental coggear 13, mounted upon a shaft 14, journaled in bearings 15, secured upon intermediate timbers 4. Segmental cog-gear 13 meshes with and drives a pinion 16, rigidly mounted upon a shaft 17, journaled in bearings 17a, secured upon timbers 3. Shaft 17 is provided at its projecting end with a feather 18 and a clutch member 19, which is slidably mounted upon the shaft, but caused to rotate therewith bythe engagingfeather 18. Said clutch member is loosely embraced bya sleeve 20, provided with oppositely-projecting pins 21, which engage slots 22 in a shifting lever 23, fulcrumed at 24 to a bracket 25, secured to the adjacent timber 3. Shifting lever 23 is provided at its opposite end with a link 26, which is pivotally connected to the short arm 27 of a hand-lever 28, fulcrumed at 29 in a bearing 30, secured to the adjacent timber 3. Hand-lever 28 is provided with a latch 3l, adapted to lock the lever in any suitable position by engaging the notched sector 32, secured to timber 3.

33 indicates a companion clutch member adapted to .be engaged by clutch member 19 and is rigidly mounted upon a shaft 34, journaled in bearings 35 and adapted to be connected with the machine to be operated.

The pitman-rod is relieved to a large extent of the compression strain incident to its downward stroke by means of a counterweight 36, suspended from the lower end of a strap 37, which is secured at its upper end to the connecting-rod by an intervening clip 38 and operates over a pulley 39, mounted upon a shaft 40, journaled in bearings 41, secured to the standards located at one end of the machine.

The operation of the machine is `substantially as follows: The reciprocating motion 0f the pitman-rod will be transmuted into oscillatory motion by the bell-crank lever, which latter, through the intervening connecting-rod 11, transmits similar motion to the segmental cog-gear 13, and as the latter swings back and forth on its axis it is evident' that it will impart an alternating rotary movement to the intermeshing pinion 16, which of course will impart a similar move- ICO ment to shaft 34 while the clutch members 19 33 are engaged. It is also evident that as the pitman-rod makes its upward stroke counterweight 36 will be elevated by the intervening mechanism; but as the pitman-rod is well adapted to resist tensile strainsthis additional duty will have little or no elfect upon it. Then as the pitman-rod makes its downward stroke and becomes subject to a compression strain, which, owing to its great length, is apt to bend or break beneath the same, the counterweight comes to its relief by assisting it in reversing the motion of the machine. The movement of shaft 34 will be stopped on disengaging the clutch members 19 33, which may be readily accomplished by throwing the hand-lever 28 over in the direction indicated by the arrow.

When the windmill is located some distance from the building containing my machine, I disconnect the bell-crank lever from the latter and fulcrum it on the windmilltower. I then connect its lower end 8d to the free end of the connecting-rod 1l, so it will impart the outward stroke to the latter on the upward movement of the pitman-rod, while weight 36 will move the connecting-rod on its inward stroke.

From the above description it is apparent that I have produced a machine which is simple in construction, durable, and thoroughly effective for the purpose intended.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

1. In a machine of the character described, a suitable frame, a bell-crank lever fulcrumed thereon, a pitman-rod pivotally connected to the short arm of the bell-crank lever, a segmental cog journaled upon the frame, a conmeeting-bar pivotally secured at its opposite ends to the long arm of the bell-crank lever and the segmental cog respectively, a weight suitably secured to the connecting-bat` and adapted to assist the pitman on, its downward stroke, and a journaled pinion which meshes with and is adapted to receive an alternating rotary movement from the segmental gear, substantially as described.

2. In a machine of the character described, a suitable frame, an extension at one end thereof, a bell-crank lever fulcrumed on the extension, a pitman-rod pivotally connected to the short arm of the bell-crank lever, a segmental cog jonrnaled on the frame, avertical arm formed integral therewith, a connecting-bar pivotally secured at its opposite ends to the long arm of the bell-crank lever and the segmental cog respectively, a weight suitably secured to one end of the connecting-bar, and a journaled pinion which meshes with the segmental cog, substantially as described.

3. In a machine of the character described, asuitable frame, a bell-crank lever fulcrumed thereon, a pitinan pivotally connected to one end of the bell-crank lever, a segmental cog journaled on the frame, a vertical arm formed integral therewith, a connecting-bar pivotally secured at its opposite ends to the vertical arm and one arm of the bell-crank lever respectively,a counterbalance-weight,a strap secured at its opposite ends to the connecting-bar and the weight, a pulley over which the strap is adapted to operate, a pinion meshing with the segmental cog, a shaft upon which it is mounted, a clutch slidably mounted upon said shaft and suitable means for operating the clutch.

In testimony whereof I aiix my signature in the presence of two witnesses.
